Naming NASA's New Spaceships
Launch vehicle: Jupiter. The new launch vehicle is intended to send humans back to the moon and then on to Mars. The Saturn launch vehicle was the big daddy of all launch vehicles and the first to send humans to another world. In Roman mythology Saturn is the father of Jupiter, and Jupiter is the lord of the skies.
Crew Exploration Vehicle: Odysseus or Ulysses. He is the hero of the Greeks in the Trojan War and the greatest traveler in ancient mythology. The CEV is intended to take humans on missions of exploration into the Solar System, perhaps the greatest travel story in modern history. The Roman version of the name, Ulysses, sounds better to this American ear and also has roots in American history with President U. S. Grant. Unfortunately, NASA has already wasted the name on an unmanned satellite. (Here.) Maybe it'll be dead by the time the CEV is ready to fly and the name will become available.
The Lunar Lander: Artemis. She is the Greek goddess of the crescent new moon. Selene is the goddess of the full moon and Hecate is the goddess of the waning moon. Artemis sounds better and Selene sounds a bit too much like the name of a certain Canadian pop singer. "Houston, we have touchdown. The Selene Dion is on the moon."

You've Gotta Love The Russians
Russia plans to have a permanent base on the Moon by 2015 and to be mining Helium 3 to run fusion reactors by 2020. Not just mining by 2020 but "industrial-scale delivery" of Helium 3.
We certainly hope there's at least one fusion reactor online by then.
If not, well there's always Dennis Wingo's suggestion that we look for the remains of asteroid impacts on Luna and mine them for their platinum group metals to fuel the hydrogen fuel-cell economy. (Here.)
There might not be gold in them thar hills but there's energy in them thar craters.
ADDENDUM: This article (here) reveals that Russia's "plans" are much more tentative than the article linked above.
People Are People Even In The Internet Age
A new study puts those fears to rest and suggests that internet users are even more connected to others than non-internet users. (Story here.)
This should not surprise.
The internet's design compels its users to interact with the rest of the world. The internet connects people to websites and people all around the world. With the mere click of a mouse a person in San Diego can read a news website published in the Persian Gulf, for example. (Here.) Email enables people to communicate easily with other people in their neighborhood, around the country, and around the world. List-serves bring people together who share common interests and enable them to arrange meetings in the real world with people they might never have met before the advent of the internet.
In fact, what the internet has done is not to drive people inward and away from other people, it has enabled users to have contact with more people and to learn more about the outside world easier than ever before. The internet is driving the world towards a future where the entire planet is our neighborhood.
The experts who worried about the internet leading to personal alienation did not understand people or the technology. They were also subjects of the "tyranny of either-or thinking." (Other examples here and here.) To either-or thinkers the internet presented a stark choice between technology and people. To both-and people the internet did not present that choice. They could both have the new technology and interact with people. Turns out that more people think "both-and" than "either-or."

Update: For Want Of An Ejector Seat?
In Mullane's defense, his point was not so much that an ejection system would have saved the Columbia astronauts. His argument was that NASA failed to learn the lesson of Challenger when it launched Columbia. In his view, NASA's failure was to permit continued launches of the shuttle with a known and dangerous design flaw. As he said, "Columbia was a repeat of Challenger, where people had a known design problem and launched anyway." (Here.)

Please, Sir, Don't You Want Some More?
For Want Of An Ejector Seat....
"'It's the most dangerous manned spacecraft ever flown,' said Mullane, who took part on three shuttle missions before retiring in 1990. 'It has no powered-flight escape system... Basically the bail-out system we have on the shuttle is the same bail-out system a B-17 bomber pilot had in World War II.' It was this lack of ejector seats that ensured the deaths of Challenger's astronauts. Such a powered escape system could have blasted them from their stricken ship and saved them."Mullane also says that
"'Columbia was a repeat of Challenger, where people had a known design problem and launched anyway.' Mullane added that astronauts deserved some share of responsibility for not pursuing safety issues more doggedly."

More Biomimetics For Space
There's been a spate of stories recently about the threat to spaceships from orbital debris. (Here for example.) Perhaps part of the solution is to make spaceships that repair themselves much like organisms heal themselves. (Here.)

Space Tourism Takes One Step Closer To Reality.

Following Through On Commercial Space Flight Opportunities.
Following up on that, NASA's Commercial/Crew Project Office recently solicited "proposals for the initial development and demonstration phase of the Commercial Crew/Cargo Project. Under this project, NASA intends to enter into agreements with private industry to develop and demonstrate the vehicles, systems, and operations needed to resupply, return cargo from, and transport crew to and from a human space facility, with the International Space Station providing the representative requirements for such a facility." (Announcement here in Word format.)
NASA isn't the only entity looking for ships to ferry crew and cargo to an orbital space station. Bigelow Aerospace is offering $50 million to anybody who flies five passengers in a spaceship to dock with a Bigelow inflatable space station twice in 60 days before January 10, 2010. (Competition rules here.)
It will be interesting to see which offer shows results first.

Human Space Flight And Human Space Exploration.
The Commercial Space Launch Amendments Act of 2004 was not about human space exploration. It was about enabling a private suborbital space industry to develop in the United States. There's a difference between exploring space, which is what the Moon-Mars Initiative is about, and opening suborbit and near Earth orbit to the commercial space industry.
For the last 30 years NASA's human space program has been about space flight not space exploration. America's astronauts have spent the last 30 years going in small circles around the Earth. Flying to LEO is a good thing. So is continously occupying the ISS. By maintaining the ISS and flying into lower Earth orbit humanity is making that region part of our home. The fledgling commercial space industry's plans for suborbit and lower Earth orbit will help to do the same. But none of it is exploration. The President's Moon-Mars Initiative is about changing NASA's focus from simply flying into space to exploring it. To oppose funding it is to oppose human space exploration.
The conservative RSC's opposition to funding the Moon-Mars Initiative in order to pay for Hurricane Katrina recovery is as bad as the classic liberal opposition to human space exploration. Liberals typically oppose it on the ground that it diverts money from social programs. Both positions sacrifice human space exploration to pay for some problem here on Earth. Both positions view human space exploration as a low-priority luxury. Both positions are short-sighted and wrong.
House Republican Politics Update.
In our view, that is insufficient. The private commercial launch industry is in its bare infancy. Its immediate goals are to break in to the suborbital and then lower orbital market. The industry is far away from being able to support human exploration of Luna or Mars. A government space program is needed for exploration and to push back the frontiers of space.

Why House Republican Politics Imperils Human Space Exploration.
Why does this matter to space exploration?
Of the three candidates only Shadegg is a member of the Republican Study Committee. (Here.) The RSC is a conservative group of an estimated 103 Congressmembers concerned about high federal government spending. After Hurricane Katrina, the RSC recommended saving money on a wide range of federal programs to pay for hurricane recovery.
Operation Offset, as it was called, resulted in a report that recommended cutting money from the space program by eliminating President Bush's Vision for Space Exploration initiative. Page 8 of the report reads:
"Cancel NASA’s New Moon/Mars Initiative(See full report here.)
In 2004, the President announced a new initiative to explore the Moon and Mars with the goal of returning humans to the Moon by 2020. NASA currently intends to use the savings from phasing out the space shuttle in 2012 to fund this program. Savings: $44 billion over ten years ($11.5 billion over five years)"
It cannot be understated how rebellious conservatives are feeling over federal spending under Republican government. RSC membership gives Shadegg credibility among conservative Republicans, both rank and file and opinion makers. (See Lawrence Kudlow on NRO here for the latter.) His membership also gives him a large base of support in the Republican Caucus. If the full RSC membership gives their support to Shadegg for leader he will be all but assured of reaching the 116 votes he needs to win. If that happens, the House will be led by a Representative who owes his victory to a group that is on record as being opposed to human exploration of space.
That's gonna hurt.
Update: Turns out that the editors of National Review Online have endorsed Shadegg. (Here.)

Engage The Hyperdrive: To Mars And Back In Six Hours?
The article makes it clear that such a drive is not close to being tested much less built. The physics that suggests such a drive is possible is not yet accepted or understood. But there are aspects to this story that give hope. The American Institute of Aeronautics and Astronautics has taken notice of the theory.
"What's more, the US military has begun to cast its eyes over the hyperdrive concept, and a space propulsion researcher at the US Department of Energy's Sandia National Laboratories has said he would be interested in putting the idea to the test. And despite the bafflement of most physicists at the theory that supposedly underpins it, Pavlos Mikellides, an aerospace engineer at the Arizona State University in Tempe who reviewed the winning paper, stands by the committee's choice. 'Even though such features have been explored before, this particular approach is quite unique,' he says."
And then there's this.
"At the moment, the main reason for taking the proposal seriously must be Heim theory's uncannily successful prediction of particle masses. Maybe, just maybe, Heim theory really does have something to contribute to modern physics. 'As far as I understand it, Heim theory is ingenious,' says Hans Theodor Auerbach, a theoretical physicist at the Swiss Federal Institute of Technology in Zurich who worked with Heim. 'I think that physics will take this direction in the future.'As the egghead captain of the Enterprise, Jean Luc Picard, would say: "Make it so!"
It may be a long while before we find out if he's right. In its present design, Dröscher and Häuser's experiment requires a magnetic coil several metres in diameter capable of sustaining an enormous current density. Most engineers say that this is not feasible with existing materials and technology, but Roger Lenard, a space propulsion researcher at Sandia National Laboratories in New Mexico thinks it might just be possible. Sandia runs an X-ray generator known as the Z machine which 'could probably generate the necessary field intensities and gradients.'
For now, though, Lenard considers the theory too shaky to justify the use of the Z machine. 'I would be very interested in getting Sandia interested if we could get a more perspicacious introduction to the mathematics behind the proposed experiment,' he says. 'Even if the results are negative, that, in my mind, is a successful experiment.'"
NASA Budget On The Chopping Block?
This Bloomberg News story (here) says that NASA's human space program might be cut to help bring America's fiscal house in order.
"The budget office also aims to reduce spending on the Space Shuttle program, slicing as much as $6 billion from the projected cost of almost $70 billion in the next four years.
Illustrating the resistance to budget cuts, members of Congress from Texas and Florida, where two of NASA's largest facilities are located, are seeking to head off trims. Republicans including former Majority Leader Tom DeLay and Senator Kay Bailey Hutchinson have written to Bush or spoken with Bolten in the past few weeks. DeLay also has lobbied Vice President Dick Cheney, according to DeLay spokesman Ben Porritt.
A reduction of as much $6 billion ``would mean the immediate retirement of the Shuttle Atlantis and a cut of the needed 19 Shuttle missions to between eight and 11 through fiscal 2010,'' a letter signed by 36 lawmakers said."
Parochial politics will play a part in how NASA's manned space program fares. Tom DeLay (The Hammer) is fast losing power in the House and he has been a powerful advocate of human space exploration. Readers of conservative commentators and websites know that Republicans in Congress and especially conservatives have reached the limit of their tolerance for big spending and big government and a move is afoot among them to return to their small-government roots. The President's Vision for Space Exploration was targeted for cuts late last year by a fiscally conservative group of Congressmembers. That effort failed. It helped to have The Hammer on NASA's side.
But that was then.
Now it is very much up in the air who will lead the House Republicans after February 2d, when the caucus is scheduled to vote. What is clear is that a revolt against big spending and big government is brewing again among the majority party in Congress. So long as the human space program is viewed as non-essential government spending its budget will be vulnerable when pennywise budgeteers start looking for places to save money.
Home Grown Radiation Protection On Mars?
Now the author of the space-oriented website Beyond Earth has suggested the same thing based on the new evidence that the magnetic fields we wrote about last year are strong enough to cause auroras on Mars. (Here.) Beyond Earth's post includes detailed information on the radiation environment found on Mars and methods for mitigating the danger.
Now if only we could get somebody to speed up the timeline for human exploration of the Red Planet.

Letting Ivan Do The Flying.
Yet from a cost perspective contracting with the Russians is not such a bad thing. According to this NASA FAQ page (here), the average shuttle flight is about $450 million.
The private launch industry in the US is not mature enough yet to compete with Russia for the job of taking astronauts to orbit. But once it is, it would certainly be in the US government's interest to pay a domestic company to do the job they are willing to pay the Russians to do. We should do more to hasten that day.
